Abstract. Although dynamic characteristics of ground penetrating radar (GPR) records are not widely applied in experimental data analysis, it is shown that they contain information about the properties of the medium reflecting its behavior in the field of high-frequency electromagnetic waves. This information used in addition to traditional analysis of kinematic characteristics allows significantly increase the efficiency of GPR survey in general.
Keywords: wave field, travel-time curve splitting, average frequency, Q-factor, multiple reflections, conductivity, dielectric permeability, absorption.
